The 90th or 50th percentile of this indicator represents the maximum length of time that 90% or 50% of patients spend in the ED until a visit disposition decision is made.

A small number is desirable for this indicator.

<div role="button" class="expandableTitle" aria-controls="backgroundRegion">Background, Interpretation and Benchmarks</div>
Rationale

Time is crucial to the effectiveness and outcome of patient care, especially for emergency patients. In conjunction with other indicators, this can be used to monitor the total time patients spend in the ED in an effort to improve the efficiency and, ultimately, the outcome of patient care.

Multiple factors can influence the indicator results, including triage level, patient population and hospital resources.

Interpretation

The 90th or 50th percentile of this indicator represents the maximum length of time that 90% or 50% of patients spend in the ED until a visit disposition decision is made.

A small number is desirable for this indicator.
